Da-nong Kim jae saeng was one of a great tea master and scholar who played a leading role in the revival of Korean tea. His perception of tea was reaching beyond the ideological, self-discipline, and Taoist dimensions of the tea-lovers owners of the time to achieve industrialization. Born as the son of a poor farmer, the consciousness of rural revival formed by almost self-made learning seems to have affected. He has published many papers, contributions, and books to suit the role of a scholar who studies tea academically. These academic activities did not stop at studying tea from a biological point of view, but went so far as to seek to expand tea cultivation areas or find ways to lead to increased farm income by reducing tea production costs. In this paper, we divided his attitude toward tea into three aspects, namely, practical use, light treatment, and benefits, while approaching, analyzing, and organizing this consciousness of Da-nong on a practical level. His academic research activities were mentioned in terms of due diligence, and his intention to export and industrialize tea in terms of light tax treatment and thus expand farm income was described. Finally, in terms of the benefit of use, we found out that drinking tea in real life encouraged the development of the mental realm and encouraged the 'five big tea spirit' through such a process.
